Using text document ALREADY uploaded on another window

[Stanfillirenfro]

Many thanks Reddy for your code.
Ii is very helpfull, although the problem is not overcome. The code you sent me deals only with the main window. In my case, and due to your help of yesterday, the problem with the main window was solved. My main problem now it to use the document on the TextEdit of the main window from childwindow withough having to upload it again.
If I have a fucntion such as "functionxxx" for example of the childwindow, how can I get the path to the text on the main window and its text? When I am compiling my initial code, the error message is that "No file name specified" and that MyMainWindow ist private in this context.

Any help? Please!

No, your main problem is that you are ignoring any information about the actual solution, i.e. what wysota is writing.

Obviously other people not reading what you are trying to achieve and posting solutions to problems you are not having doesn't help either.

So either share the QTextDocument created by your main text edit with the secondary one, or create a stand alone QTextDocument and use it on both text edits.

Cheers,

I think the real problem is that the OP has only a minimal understanding of C++ programming in general and has no idea how to implement the suggestions being posted. He is way over his head with this project and needs to stop asking us basic C++ questions and start by reading a good C++ textbook until he understands some basic concepts.

There is no magic to using the Qt class library; it is just C++ classes in the end, and if you don't understand the basics of passing C++ instances around a program either by pointer or by reference, you won't be able to write any C++ program, much less a Qt program.
